Problems solved by technology

Due to the irregular shape of the part to be repaired on the dentition model, it is difficult to measure with a ruler, the operation process is cumbersome, and the measurement accuracy is not good. After the measurement, it is often necessary to rely on experience for secondary processing of the data
[0004] To sum up, the current intraoral and model space analysis relies on clinical experience, and lacks accurate and efficient measurement methods, clear measurement methods and standards.

Embodiment 1

[0042] A measurement system for space analysis of oral implant restoration, including: the first measurement component for measuring the opening degree and the gap between multiple missing teeth, the second measuring component for measuring the gap between single missing teeth and the occlusal distance, and for measuring The third measuring component of the gingival penetration depth, the first measuring component, the second measuring component and the third measuring component all include an independent connecting rod and a measuring head arranged on the upper end of the connecting rod, that is, each measuring component has a A connecting rod and a measuring head, the measuring heads of the three measuring components are different, and the connecting rod can be the same. In this embodiment, the shapes of the connecting rods of the three measuring components are all the same.

[0043] Such as figure 1 As shown, the connecting rod 4 is a curved long rod, including a connectin...

Embodiment 2

[0054] On the basis of Embodiment 1, this embodiment also further improves the connecting rod 4:

[0055] When the middle connecting rod 4b2 is inclined toward the negative semi-axis direction of the z-axis, it is also inclined toward the negative half-axis direction of the x-axis, that is, backward, so that the middle connecting rod 4b2 and the lower connecting rod 4b1 are still in the xy plane An included angle C is formed on the top, and the angle of the included angle C is between 120°-180° and not equal to 180°, that is, the angle between the middle connecting rod 4b2 and the positive semi-axis of the y-axis is not greater than 60°, in other words the middle connecting rod 4b2 is also tilted backwards, within 60°.

[0056] The projections of the upper connecting rod 4b3 and the middle connecting rod 4b2 on the xy plane are as follows Figure 7 As shown, 5 is the projection of the middle connecting rod 4b2 on the xz plane, and 6 is the projection of the upper connecting r...

Embodiment 3

[0059] This embodiment is a further improvement of Embodiment 1, and provides specific dimensions for the measurement system of Embodiment 1 for the analysis of the dental implant restoration space.

[0060] (1) connecting rod

[0061] In this embodiment, the structures and sizes of the connecting rods of the first measuring component, the second measuring component and the third measuring component are completely the same. In other embodiments, the size of the connecting rods of one or more of the measuring components can be adjusted according to the needs of use.

[0062] In this embodiment, the connecting rod such as Figure 5 As shown, the lower end of the connecting rod 4 is a connecting cylinder 4a with a length of 5mm and a diameter of 3mm, and the connection between the connecting cylinder 4a and the connecting rod body 4b is a hexagon 4c with a height of 2mm and a side length of 2mm; The long rod has a cross-section of a square with a side length of 3mm. The connect...

Abstract

The invention discloses a measuring system for oral implant repair space analysis. The system comprises a first measuring unit for measuring degree of opening and a plurality of missing teeth gaps, asecond measuring unit for measuring a single missing tooth gap and bite distance, and a third measuring unit for measuring depth of gingiva. The first measuring unit, the second measuring unit and thethird measuring unit all comprise connecting rods and measuring heads arranged at upper ends of the connecting rods. The measuring units of the measuring system have simple structures, are easy to use, have accurate measured data, can accurately and rapidly measure specific spatial characteristics of a to-be-repaired position, and provides basis for design of key parameters of implant size, implant location or shape and structure of upper dummy and the like, and solves problems that current oral and model space analysis depends on clinical experience, is lack of accurate and efficient measurement methods.

Description

technical field [0001] The invention relates to the technical field of dental implant restoration space analysis, in particular to a measurement system and method for oral implant restoration space analysis. Background technique [0002] Dental implants are favored by patients with missing teeth because they do not damage natural teeth, are highly comfortable, and have good aesthetic effects. They are also one of the important means of restoring lost teeth. Dental implant technology has been developed for more than 40 years. In the continuous development, clinicians and scholars have gradually explored more scientific and reasonable treatment plans and techniques through the accumulation of cases and experimental research, which has gradually increased the success rate of dental implants after surgery. The most commonly used dental implant consists of two parts, including an implant located in the jawbone and an upper restoration located in the oral cavity. At the same tim...
